This non-provisional application claims priority to pending provisionalapplication No. 62/591,449 filed on Nov. 28, 2017, all of which areowned by the same inventor.

BACKGROUND OF THE INVENTION

The floating case generally relates to camera accessories and morespecifically to cases, such as holders, for computer memory cards thatfloat.

Early computers operated upon punched cards. The cards had a weight ofcardstock and a distinctive shape. The punched cards contained programinstructions in a certain sequence. Cards that fell out of ordercorrupted a program loaded into a computer. Programmers would usevarious tactics to keep cards in order such as a drawing made upon anedge of a deck of punched cards. Time has overtaken the punched card.

Programs and data load then loaded upon computers using cassette tapesand floppy disks. The cassette tapes came from the music recordingindustry and the floppy disks developed from winchester drives. Thefloppy disks had a thin polymer envelope generally back. People labeledfloppy disks using a variety of adhesive labels commonly available atoffice supply outlets. In time, floppy disks decreased in size to 3½inch width and increased capacity to 1.44 MB. However, software and datacontinued to multiply.

Vendors of computer products and eventually users of computers placedprograms upon optical discs read by various drives. The optical discsgenerally had a translucent, or transparent in some instances,appearance. The optical discs reached read write ability andapproximately 720 MB storage capacity. However, software and datacontinued to multiply.

With the advent of the Internet and build out of communicationsnetworks, vendors and users of programs and data transmitted boththrough the Internet. The transmissions occurred as email attachments,file transfer protocol uplinks, and direct connection, computer tocomputer, on a local area network. Presently, cloud storage has becomeavailable where programs and data reside on immense third party serversand vendors and users of programs and data access programs and dataremotely.

However, accessing cloud storage calls for a robust communicationsnetwork. In the absence of such a network, the programs and data in thecloud become inaccessible. Without a nearby tower or a clear line ofsight, cloud data does not display upon wifi devices such as smartphonesand tablets.

Meanwhile, solid state memory devices have developed. These devicesstore programs and data on drives without moving parts. These deviceshave ever growing capacities presently about 128 GB. Such devices canhold plenty of programs and data. The devices often take the form ofcameras suitable for digital photography. Digital cameras utilize selectoptical lenses and digital imagery to capture scenes whether still or inmotion. Depending upon resolution, a digital camera may have many lowresolution pictures in a storage device or few high resolution picturesin a storage device. A series of digital pictures forms an eventualmovie. Such a series has plenty of pictures. Presently, people takeplenty of pictures with digital cameras. More often than not, peoplefill a storage device, or memory card, with pictures more quickly thanplanned. Photographers and videographers on locations readily fillmemory devices. Such persons quite often find themselves handling manymemory devices and struggling to store them. Such persons near waterface the additional risk of a memory device becoming submerged and neverbeing seen again. Alas, the picture or movie on a lost memory device mayhave a high value.

DESCRIPTION OF THE PRIOR ART

Traditionally, people have collected memory devices, hereinafter SDcards, in one place and then packaged the SD cards. The packaging may bean envelope, box, vinyl sleeve, various holders, and the like. Eachperson organizers his cards in his own way. With SD cards multiplyingthrough usage and plenty of picture taking, a person quickly has many SDcards to store, retrieve, and manage. SD cards come in select sizesestablished by their manufacturer in coordination with device makers.Generally the sizes are small compared to a person's fingers, typicallya large size about the shape of a postage stamp and a small size aboutone quarter the stamp size. Such small items readily succumb to loss andprove difficult to label or otherwise mark.

The present invention overcomes the difficulties of storing andorganizing a plurality of memory devices, such as SD cards, subject toexpanding data needs particularly near water. The present invention hasits device that prevents submerging in water and allows a user to seethe device and retrieve it.

SUMMARY OF THE INVENTION

Generally, the present invention provides a device with a rigid layerand a joined buoyant layer. The rigid layer has at least one chamber fora larger memory card and at least one minor chamber for a smaller memorycard. Each chamber and minor chamber has a pair of first tabs, a pair ofsecond tabs, and a foot that secure a memory card placed into eachchamber and minor chamber. The buoyant layer displaces water so that thedevice floats and preferably has the rigid layer floating above a watersurface. The device and its layers have a left end, a right end, afront, a back, a top surface, a bottom surface, a first corner and atleast one second corner. The rigid layer and the buoyant layer have awaterproof construction and the buoyant layer has a low weight to volumeratio. For safekeeping, in an alternate embodiment, the device has ahole through its top surface and the bottom surface for a lanyard.

Forgetful or clumsy as some people can be, people will choose a devicethat helps remedy those misgivings, particularly around water. Thepresent invention stores the abundance of memory cards filled duringshooting of a digital movie. The present invention also floats on waterso that memory cards stored upon it do not sink to the bottom of a bodyof water, never to be found.

The present invention applies immediately in the memory card,photographic, video, and movie industries as more and more users takedigital cameras upon, into, and around water. The present inventionutilizes a layer of selected density and a rigid layer that receivesmemory including but not limited to SD cards, microSD cards and SIMcards.

The present invention utilizes two principles. First, being the naturaldisplacement of water from a volume and second, that that volume ofwater exceeds the weight of a combined buoyant layer, rigid layer, andmemory card cargo. The buoyant layer remains closed and does not becomewet and soggy. While the rigid layer stores the memory cards above thebuoyant layer.

There has thus been outlined, rather broadly, the more importantfeatures of the invention in order that the detailed description thereofthat follows may be better understood and that the present contributionto the art may be better appreciated. The present invention alsoincludes self righting capability, additional chambers, additional minorchambers, and variations in buoyancy from positive to neutral.Additional features of the invention will be described hereinafter andwhich will form the subject matter of the claims attached.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The present art overcomes the prior art limitations by providing afloating case for memory cards of electronic equipment, typicallycameras. The present invention provides a case with sufficientdisplacement so that it floats when fully loaded with the heaviestmemory cards.

FIG. 1 shows a top view of the invention 1 having a size similar to thatof a North American credit card, though not confined to that size. Theinvention, or case, has a generally rectangular shape with a front 2 anda mutually parallel and spaced apart back 3, and a left end 4 and amutually parallel and spaced apart right end 5. The invention has alength, generally the long dimension of the invention here shown as leftto right, and a centerline parallel to the length, that is, the frontand the back. The left end and the right end are generally perpendicularto the front and the back as shown. The back and the left end merge at afirst corner 6 and the left end and the front merge at a second corner7. The front and the right end, and the right end and the back also eachmerge at a second corner 7 as well. The first corner and the secondcorners generally have a rounded shape. A top surface 8 spans betweenthe left end and the right end, and the front and the back, and occupiesthe foreground in this view. The top surface near the first corner has ahole 9 through the device that receives a lanyard or other keeper, notshown. The top surface also has a chamber 10 inwardly from the secondcorner 7 at the merge of the left end 4 and the front. The chamber has anearly rectangular shape with its length oriented transverse to thelength of the device. Along the front outwardly from the chamber andtowards the right end, the top surface has a plurality of minor chambers11, here shown as five in number. The minor chambers also have a nearlyrectangular shape but with a length slightly less than half of thelength of the chamber 10 and a much narrower width. Opposite the minorchambers 11 upon the front 2, the invention 1 has another set of minorchambers 11 upon the back 3 generally in registration as shown. The setsof minor chambers appear as rows outwardly from the chamber. The minorchambers receive a small size memory card and the chamber receives alarge size memory card.

More particularly, the chamber 10 has a volume recessed into the topsurface 8 of sufficient depth for a memory card. The chamber then hasfirst tabs 12 generally mutually opposite and outwardly from thecenterline and one first tab locating near a second corner and twosecond tabs 13 inwardly from the first tabs. The first tabs and thesecond tabs have the same length measured parallel to the left end 4 andthe same depth measured parallel to the front. The first tabs and thesecond tabs have a thickness less than that of the top surface 8 so thata memory card may slide beneath the first tabs and the second tabs andrest within the top surface. The first tabs and the second tabs have aspacing from the chamber, that is, the bottom of the chamber, so amemory card may insert. Outwardly from the first tabs towards the front,the chamber has a tongue 20 of a small rectangular shape extendingoutwardly from the centerline. The tongue separates upon three sidesfrom the top surface as a cantilever so that it bends slightly duringuse. The tongue 20 has a small lip 14 proximate the front 2 so that amemory card may rest against the lip and prevent the card from slidingout of the chamber. The lip extends upwardly and opposite the buoyantlayer.

And more particularly, each minor chamber 11 also has a volume recessedinto the top surface of sufficient depth for a small memory card,typically the same depth as the chamber 7. The minor chamber also hasfirst tabs 12 generally opposite and two third tabs 15 inwardly from thefirst tabs and forming a corner of the minor chamber. The first tabs andthe third tabs have the same length measured parallel to the left end 4and the same depth measured parallel to the front. The first tabs andthe third tabs of the minor chamber have a thickness less than that ofthe top surface 8 so that a small memory card may slide beneath thefirst tabs and the third tabs and rest within the top surface. The firsttabs and the third tabs have a spacing from the minor chamber, that is,the bottom of the minor chamber, so a memory card may insert. Outwardlyfrom the first tabs towards the front, or alternatively the back asshown, each minor chamber also has a tongue 20 of a small rectangularshape extending outwardly from the centerline. The tongue separates uponthree sides from the top surface as a cantilever so that it bendsslightly during use. The tongue 20 has a small lip 14 proximate thefront 2, or the back 3, so that a small memory card does not slide outof the chamber. Adjacent minor chambers have their first tabs 12 andthird tabs 15 generally upon a common spine or divider as shown. Beneaththe lips, another layer may be seen in this figure. As before, each lipextends upwardly and opposite the buoyant layer. In the preferredembodiment, the invention has one chamber towards the left of the front,a row of five minor chambers to the right of the chamber, and a secondrow of five minor chambers opposite the first row, that is, towards theback, as shown. The preferred embodiment has the lips aligned for eachrow of minor chambers and the lips of the first row aligned with the lipof the chamber. Because of the chamber and the minor chambers, theinvention may hold memory cards of two sizes.

FIG. 2 shows a bottom view of the invention with its bottom surface 16in the foreground. The bottom surface generally extends upon the entireinvention from the left end 4 to the right end 5, and the front 2 to theback 3 and also follows the first corner 6 and the second corners 7 asshown. The bottom surface also admits hole 9 through it for a lanyard,not shown, as previously described. The bottom surface contributes tothe floatation ability of this invention.

Turning the invention, FIG. 3 shows the left end 4 in the foreground anda second corner 7 to the left and a first corner 6 to the right. Thechamber 10 opens in the top surface 8 to the right as well. The topsurface 8 is the uppermost surface of a rigid layer 17, typically planarand flat, typically polymer though other materials may see use, that hasthe chamber 10 and minor chambers 11 formed therein. The rigid layer hasits thickness measured normal to the top surface. The chamber shown herehas a slight recess inwardly from the first corner 6. This occursbecause a first tab 12 has its inwardly location from the first cornerwhich causes an apparent step in the width of the rigid layer.

Beneath the rigid layer, the invention has a buoyant layer 18 with thebottom surface outwardly from the invention and opposite the top surface8. The buoyant layer joins to the rigid layer from the left end to theright end and from the front to the back as previously shown in FIG. 2,except for the hole 9. The buoyant layer has a waterproof joining to therigid layer such as by resins, adhesives, cohesives, thermal welding andselect mechanical fastening such as punching or riveting. The buoyantlayer generally also is waterproof itself and does not admit water intoits construction. The buoyant layer joins the rigid layer beneath thechamber and the minor chambers. The buoyant layer creates additionaldisplacement, that is, volume of the device but at little increase inweight. The buoyant layer operates to float the invention on freshwaterand on saltwater when loaded fully with memory cards. The buoyant layerdisplaces a volume of water that exceeds the weight of itself, the rigidlayer, and the memory cards stored onboard. In the preferred embodiment,the buoyant layer lifts the rigid layer completely above the surface ofwater upon immersion of the invention. In an alternate embodiment, thebuoyant layer prevents the top surface from immersing into the surfaceof water upon deploying the invention.

More particularly, for the Floating Case, its center of gravity shouldbe above its center of buoyancy, shown by a distance y_(bg). Center ofbuoyancy is the center of gravity for the water volume displaced by anobject, here the case, as at V. Center of gravity is from the weight ofthe case 1 itself plus any cargo, such as SD cards, as at I. When thecase tips to either side on water, its center of gravity above thecenter of buoyancy causes the case of the invention to right itself.This self righting happens when the buoyant force of the tipped caseintersects the tipped case's centerline at a point called themetacenter, generally above the case a distance as at h_(m). TheFloating Case of the present invention keeps a portion of its front 2,back 3, left end 4, and right end 5 and as much of its top surface 8above water as possible as suggested by the following equation:

$\begin{matrix}{h_{m} = {\frac{I}{V} \pm y_{bg}}} & {{Equation}\mspace{14mu} 1}\end{matrix}$

At a minimum the invention has neutral buoyancy when loaded in thechamber and each minor chamber. Preferably, the invention has positivebuoyancy when loaded in the chamber and each minor chamber with memorycards. That is, the invention has a density less than that offreshwater. Preferably, the invention self rights. During use whenloaded with memory cards, the invention has a draft less than fifty percentum of its thickness 22 later shown in FIG. 7.

Turning to the other end, FIG. 4 shows the right end 5 in theforeground. This end 5 appears generally symmetric with two spaced apartsecond corners 7 and the buoyant layer 18 spanning between them. Therigid layer joins to the buoyant later but has two minor chambers 11formed near the second corners. The minor chambers shown opening hereappear to have a slight recess inwardly from the second corners 7because their first tabs 12 have their inward location from the secondcorner which causes an apparent step in the width of the rigid layer atthe front 2 and the back 3 as shown. The buoyant layer has its samedimensions and buoyancy characteristics as described above.

Rotating the invention once more, FIG. 5 presents the front 2 in theforeground with the chamber 10 to the left and five minor chambers 11spaced towards the right. The chamber and each minor chamber have theirlips 14 forward and terminating at the front. The front spans from theleft end 4 to the right end 5 as shown with the chamber towards the leftend and the last minor chamber towards the right end. The chamber hasits depth here shown as slightly greater than the depth of the adjacentminor chambers. The minor chambers each have a pair of first tabsorienting inwardly for each minor chamber. Then the chamber has its pairof first tabs 12 orienting inwardly for it and the first tabs of thechamber and the minor chambers appear coplanar. Also, each tongue andappurtenant lip may deflect in its chamber and minor chamber so that itbends downward, towards the buoyant layer, upon insertion of a memorycard over the lip of each tongue and then rebounds upwardly, away fromthe buoyant layer as the lip grips the bottom edge of a memory card forsecurement.

FIG. 6 shows the back 3 of the invention in the foreground. The back hasfive minor chambers 11 shown at the left of the figure and extendinginwardly but not reaching the first corner 6 at the left end 4, here tothe right of the figure. Each minor chamber 11 has its lip 14 at theback. Each tongue bends downwardly to receive a memory card and thenreturns upwardly so its lip engages the bottom edge of a memory cardsecurely against sliding out from the invention.

And, FIG. 7 has a sectional view through the invention generallyparallel to the right end 5 and the left end 4. This view extends fromthe lips 14 of the front to the lips 14 of the back. Each tongue 20 hasa lip 14 a generally outwardly from the remainder of the invention. Thelip has the largest thickness upon the tongue 20. From the lip inwardly,the tongue has a lesser thickness than the lip but at least three timesas long as the lip. The tongue behind each lip extends inwardly in theplane of the minor chamber 11. The lip is upon the bottom of the minorchamber and spaced below the first tabs 12 previously shown. The spacingbetween the tongue and the bottom of the minor chamber admits an SD cardtherein while the lip has sufficient thickness to grip an edge of an SDcard. The minor chambers extend into a spine 21 of the invention thatdefines the thickness of the rigid layer 17 that exceeds the height ofthe minor chamber. The spine extends from the right side 5 to an insideof the chamber 10 as previously shown in FIG. 1. Beneath the spine 21and the minor chambers 11 in this figure, the invention has its buoyancylayer, or float 18, as before. The float extends beneath the entirespine 21, the tongues 20, the lips 14, the minor chambers 11, andapproximates the typical credit card shape. The buoyant layer has athickness as at 22 generally less than the thickness of the spine 21.

From the aforementioned description, a floating case has been described.The floating case is uniquely capable of floating a collection of memorycards so that a user may see the invention and retrieve it from anaqueous related location, such as a river, lake, ocean, beach, and thelike. The floating case may see application upon devices manufacturedfrom many materials, beyond those preferred, including but not limitedto, polymers, polyvinyl chloride, polyethylene, polypropylene, urethane,nylon, rubber, latex, steel, ferrous and non-ferrous metals, theiralloys, and composites.

As such, those skilled in the art will appreciate that the conception,upon which this disclosure is based, may readily be utilized as a basisfor the designing of other structures, methods and systems for carryingout the several purposes of the present invention.
